标题:Synthesis of dihalohydrins and tri- and tetra-substituted olefins

权利人:UNIV TEXAS
摘要:A novel synthesis reaction for highly stereospecific tri- and tetra-substituted olefins is described. A single stereoisomer of stable α-halo-α,β-ester is produced in high yield by the reaction of aldehyde or ketone with a trihalogenated compound such as trichloroacetate in the presence of CrCl 2 in a solvent. By varying the amount of CrCl 2 used, the stable dihalohydrin intermediate may be obtained as well.

发明人：BATISI JACOBUS N M; MARX ARTHUR F
权利人:GIST BROCADES NV
摘要:New 9α-hydroxy-17-methylene steroids are prepared by the introduction of a substituted 17-methylene group in 9α-hydroxyandrost-4-ene-3, 17-dione. n The resulting compounds are useful starting compounds in the synthesis of corticosteroids.

摘要:N-acyl modified sialic acid (α-(2→6))-D-aminopyranose derivatives, their synthesis methods and uses are disclosed. Sialic acid (α-(2→6))-D-aminopyranose derivatives represented by formula 1 are synthesized by using D-aminogalactose (glucose) and sialic acid as raw materials, which are coupled with carrier proteins or polypeptides to obtain glycoprotein (glycopeptide) conjugates. Acetyl is replaced by derivative acyl in the structures of said compounds, therefore the compounds show good activity in antitumor vaccines.
